### Instruction:
What is the kinetic energy of an object with a mass of 3kg and a speed of 15m/s?

### Response:
assistant
The kinetic energy (KE) of the object is calculated using the formula KE = 0.5 * mass * speed^2. Therefore, the kinetic energy of the object with a mass of 3kg and a speed of 15m/s is 675 Joules.
